Adjust D/A Conversion Curve
You can adjust the conversion curves according to the actual needs by changing the Offset value (CR#32 ~ CR#33) and
Gain value (CR#38 ~ CR#39).
Offset: The corresponding voltage/current input value when the digital output value = 0.
Gain: The corresponding voltage/current input value when the digital output value = 16,000.
